Fields

Duplex Out

This field is used to indicate losses or gains between the DUPLEX OUT port and the device-under-test.

•Enter a positive value to indicate a gain (such as an amplifier gain). The RF Generator’s level is automatically set that amount below what is indicated in the RF Generator’s

Amplitude field. (Example; if this value is 10 dB, and the Amplitude field shows 0 dBm, the actual level out this port is −10 dBm.) The value at the output of the external

amplifier should then be at the level indicated in the Amplitude field.

•Enter a negative value to indicate a loss (such as cable loss). The RF Generator’s level is automatically set that amount above what is indicated in the RF Generator’s Ampli- tude field to compensate. The value at the opposite end of the cable (loss) should then be at the level indicated in the Amplitude field; unless the resulting RF Generator setting exceeds the maximum output level, then an error occurs: Input value out of range. In that case, reduce the Amplitude setting, or decrease the Duplex Out value.

GPIB Example

“CONF:OFL:DUPL -1”

enters a path loss of 1 dB between the DUPLEX OUT port and the mobile station.

This field is only used when the RF Level Offset field is set to On.
